PRODUCT DETAIL
Features:
If you’re refreshing the top end of your 7.3L Powerstroke or chasing a little more durability under pressure, the Cometic C5839-080 MLS Head Gasket is a smart, performance-ready upgrade. Built to handle the heat and stress that diesel engines are known for, this gasket delivers peace of mind whether you're towing a heavy load or building out a high-mileage workhorse. Its .080-inch thickness and 4.140-inch valve-pocketed bore are perfect for custom setups or precision rebuilds where maintaining cylinder pressure is key. This isn’t some run-of-the-mill gasket either, it’s reinforced with premium materials like armor-clad, graphite, and galvanized steel to tackle the uneven sealing surfaces common in older or worked-over blocks. The five-layer MLS design offers rock-solid strength and flexibility to seal tight under extreme combustion conditions. It fits all 1999-2003 Ford F250 and F350 Super Duty trucks with the legendary 7.3L Powerstroke, making it a dependable choice for diesel owners who know what real durability feels like. If you’re chasing long-term reliability with a side of confidence, this gasket gets it done.
The Cometic C5839-080 is a multi-layer steel head gasket specifically designed for the 1999-2003 7.3L Powerstroke engine, providing an ideal combination of strength, flexibility, and precision fitment. With a 4.140-inch valve-pocketed bore and .080-inch compressed thickness, this gasket is well-suited for engines running custom tolerances or undergoing rebuilds where thicker sealing is required. Its five-layer construction allows it to manage high combustion pressures while resisting the thermal expansion and contraction that can lead to gasket failure. Materials like galvanized steel, graphite, and armor-clad reinforcement provide excellent sealing across irregular or imperfect surfaces, especially in applications where cylinder heads or blocks have seen extensive use. The gasket is not side-specific, making installation more straightforward in tight engine bays. It’s an excellent fit for both stock and modified builds where consistency, strength, and long-term sealing are essential. Built to handle the harsh operating environment of diesel engines, this Cometic MLS gasket ensures your Powerstroke continues running strong mile after mile.
Fits: 1999, 2000, 2001, 2002, 2003 Ford F250/F350 7.3L Powerstroke
